What is Data Unification and Why Is It Important?

In today’s data-driven world, organizations face the challenge of managing vast volumes of data from multiple sources. Master data management (MDM) solutions, such as Profisee, offer a robust framework for addressing this challenge by unifying data to create a single, accurate and consistent view of information.

In this blog post, we’ll delve into the concept of data unification, exploring its importance, key differences from traditional MDM approaches, steps involved, best practices, common challenges and how Profisee MDM can assist organizations in achieving seamless data unification.

What is Data Unification?

At its core, data unification refers to the process of integrating data from multiple sources into a single, coherent view.

This involves bringing together data from various systems, databases and applications to create a unified dataset. The goal is to resolve inconsistencies, redundancies and discrepancies in the data, providing users with a consistent and reliable view of information.

Understanding Data Unification in the Context of MDM

Data unification is a critical aspect of MDM that focuses on integrating and harmonizing data from multiple sources to create a unified dataset.

Unlike traditional MDM approaches, which primarily involve managing master data entities, data unification extends beyond master data to include all types of data across the enterprise.

While MDM encompasses various processes — including data unification — it represents a broader framework for managing master data entities comprehensively.

For example, data unification focuses on integrating and harmonizing data while MDM involves additional processes such as data governance, data quality management and data stewardship. MDM ensures that master data entities are governed, maintained and used effectively throughout their lifecycle, providing a foundation for data-driven decision-making and operational efficiency.

The Importance of Data Unification

Data unification plays a crucial role in modern data management for several reasons. For starters, having a unified view of data enables organizations to make better-informed decisions.

Deeper Insights

By consolidating data from disparate sources, businesses can gain deeper insights into their operations, customer data and market trends.

For example, a company that is growing rapidly through acquisition may accumulate considerable “technical debt” of databases, applications and systems from the new subsidiaries. To glean true enterprise-level insights, executives would need to analyze supplier relationships, raw materials costs and customer behavior across all source systems — not just those at the legacy or highest-level company.

Ability to Identify Opportunities

Armed with a holistic, unified view of their business, companies can then identify opportunities, mitigate risks and drive growth.

Specifically, customer data unification can facilitate enhanced customer experiences. By integrating customer data from various touchpoints — regardless of whether it’s a support interaction managed by one team or a marketing email managed by another — organizations can gain a comprehensive understanding of their customers’ preferences, behaviors and needs. This allows them to deliver personalized and targeted experiences, ultimately using customer data to improve satisfaction and loyalty.

Breaking Down Data Silos

Additionally, data unification helps organizations break down data silos. In many companies, data is scattered across different departments, systems, and formats, making it challenging to access and leverage effectively. By unifying data, organizations can overcome these silos, enabling better collaboration, data sharing and alignment across the business.

Components of Data Unification

Back to top ↑

There are a few discrete steps and components to unify data, including:

Data Profiling

The process of data profiling involves analyzing data sources to understand their structure, quality and content. This involves identifying anomalies, inconsistencies and data quality issues that need to be addressed.

In data profiling, the frequency and distribution of data values are measured on relevant structural levels. Data profiling can also be used to discover the keys that relate to data entities across different databases and to the degree that this is not already done within the single databases.

Data profiling can directly measure data integrity and be used as input to set up the measurement of other data quality dimensions.

Data Cleansing

Data cleansing involves correcting errors, inconsistencies and duplicates in the data to ensure its accuracy and reliability. This may involve processes such as data validation, deduplication and enrichment.

Often, commercial tools can help correct or remove errors and inconsistencies within the data. They can automatically standardize formats, eliminate duplicate records and address missing or inaccurate data values, improving data accuracy and completeness.

Data Integration

Data integration involves bringing together data from different sources into a unified dataset. This involves mapping data fields, resolving conflicts and ensuring compatibility between data sources before they are joined or appended within a database of synchronized data.

Both purpose-built extract, transform and load (ETL) systems and data quality management (DQM) tools exist for integration workloads. Commercial, cloud-native MDM platforms can also be considered comprehensive data unification platforms that also include enterprise integration functionality for building a comprehensive master data model to power downstream analytics from synchronized data.

Data Standardization

Data standardization includes normalizing data formats, structures and values to ensure consistency across the unified dataset. This may include standardizing naming conventions, units of measurement and data formats.

By standardizing data, organizations can improve data quality, accuracy and reliability, laying a trusted foundation for effective decision-making and operational efficiency.

Data Matching and Merging

Matching, merging and survivorship is the process of identifying and resolving duplicates or conflicting records to create a golden record or master data entity. Customer data unification often also includes the process of identity resolution to accurately determine whether multiple records with similar data are, in fact, a single person.

This involves comparing data records, establishing matching criteria (often using fuzzy matching) and merging or consolidating duplicate records. Data synchronization between systems is also often achieved in an operational implementation style.

Data Governance

Data governance involves establishing policies, processes and controls to manage and maintain the unified dataset effectively — with the end goal of ensuring high quality through the complete lifecycle of your data.

This includes defining data ownership, access rights and data quality standards, as well as implementing mechanisms for data lineage, auditability and compliance.
